@aunr f u/4099190 United States Patent BINDING INSTRUMENT DonatGuignard, Sainte-Croix, Switzerland Application May 20, 1953, Serial No.356,243 Claims priority, application Switzerland June 13, 1952 4 Claims,(Cl. 140-119) My invention has for its object a binding instrumentincluding a body provided with a handle and two lugs registering witheach other and carrying a bar adapted to move longitudinally against theaction of elastic means, said bar being provided with a hook at one end,while means are provided for imparting a rotary movement to said barwhen it is being shifted longitudinally so as to wind over one anotherthe ends of a brace engaging the hook.

I have illustrated in the accompanying drawing, by way of example, apreferred embodiment of my improved binding instrument. In said drawing:

Fig. l is a lateral elevational view of the binding instrument;

Fig. 2 is a sectional view through line I--I of the instrument shown inFig. 1; and

Fig. 3 is a side view of a modified detail of said instrument.

The instrument illustrated in Figs. 1 and 2 includes a body 1 to whichis secured a handle 2 that is riveted thereto at 3. The body 1 includesat each end a perforated or apertured lug 4 and 5 respectively, saidlugs registering with each other and slidingly carrying a square bar 6;a section of the latter is twisted round its longitudinal axis so as toform a screw having a very long pitch and adapted to engage acorresponding tapping or formation provided inside the lug 5. The bar 6carries at one terminal or end a hook 8 projecting beyond the lug 5 andat the other terminal or end a pin 9 forming an abutment and it carriesfurthermore, in its untwisted section, a stop 10 adapted to be engagedby one end of a return spring 11 the other end of which engages thetapped lug 5.

To the body 1 is pivotally secured, through the agency of a spindle 12,a bell crank 13 the arm 14 of which is adapted to be grasped by handtogether with the handle 2. The handle and the bell crank thuseffectively constitute a pistol grip for the body of the instrument. Acoil spring 15 is fitted between the body 1 and the other arm 18 of thebell crank so as to urge said parts away from each other. A stud 16carried by the body 1 limits the angular shifting of the bell crank 13away from the handle 2, While the arm 18 of said ,bell crank carries astop, nose or lock 17 adapted to engage the stop 10 and to hold thus thebar 6 fast temporarily in its foremost position,

The outer or free end 19 of the arm 18 forms the mov able arm of pliersthe cooperating stationary arm 20 of which is rigid with the body 1. Inorder to further the angular shifting of the bell crank 13, the latteris clamped over the spindle 12 by means of a nut 21 through the agencyof an elastic washer 22 (Fig. 2).

The body 1 carries a cutting blade 23 which may serve for the cutting ofa bough if desired.

The instrument illustrated in Figs. 1 and 2 which is intended moreparticularly for securing the boughs of vine, tomatoes, espalier treesor the like by means of a wire or reinforced string, is operated asfollows:

The two ends of a brace surrounding the stems or "ice boughs of theplant to be considered, are fitted over the hook 8 on which they areheld by hand after which the body 1 is drawn in by means of the handle2. This causes the hook 8 to revolve as a consequence of the relativelongitudinal movement assumed in the direction of' the arrow 24 by thebar 6 which is ultimately locked by the crank arm 13, when the latter isshifted by hand so that the stop 17 thereon may engage the rear surfaceof the stop 10. While the rod 6 is thus held fast in its foremostposition, the operator releases the hook 8 with reference to the ends ofthe brace, which ends said hook has wound over each other. This beingdone, the operator releases the crank arm 13 which pivots under theaction of the coil spring 15 so as to shift the stop 17 back away fromthe stop 10. Consequently, the bar 6 returns into its starting positionunder the action of the spring 11 and the operator then engages the endsof the brace between the plier arms 19 and 20 with a view to cuttingthem therebetween.

Fig. 3 illustrates a modification of the arm 18 of the bell crank 13,which latter carries pivotally the stop 17 through .the agency of a pin25, said stop being urged into the operative position illustrated by thespring 26 wound round the pin. One end of said spring abuts against apin 27 rigid with the bell crank 13 while its other end engages anopening 28 formed in the stop 17; the latter may be caused to pivot inthe direction of the arrow 29 so as to ride over the stop 10, but itsreturn rotation in the opposite direction is stopped by the pin 27 sothat overshifting of the stop 10 in a direction opposed to the arrow 29,is prevented.

I have provided in a further modification for the use of a bar 6 havinga helical groove engaged by a stud secured to the body 1.

It is also possible to connect the stop 10 with a flange carried by thebody 1 through the agency of an elastic return member such as a springor an elastic wire.

Lastly, it is also possible to secure to the end 19 of the arm 18 of thebell crank an independent removable cutting blade adapted to cooperatewith the stationary arm 20 for cutting a brace.

Various changes and modifications may be made without departing from thespirit and scope of the present invention and it is intended that suchobvious changes and modifications be embraced by the annexed claims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is:

1. A binding instrument comprising a body having two ends, a handleprojecting from said body, first and second perforated lugs rigid withsaid ends of said body, respectively, a bar slidably carried in theperforations of said lugs, respectively, and having first and secondterminals extending beyond said first and second lugs, respectively,hook means on said first terminal of said bar, pin means on said secondterminal of said bar for limiting longitudinal movement of said bar inone direction, stop means on said bar intermediate said lugs forlimiting longitudinal movement of said bar in opposite direction, springmeans about said bar between said first lug and said step means,cooperating formations on at least one of said lugs and on said bar,respectively, for causing rotation of said bar when longitudinallydisplaced relative to said lugs, bell crank means pivotally secured tosaid body, and lock means on said bell crank means, said bell crankmeans and said handle together forming a pistol grip for saidinstrument, whereby upon relative dsiplacement between said body andsaid bar to compress bell crank means thereafter efiecting release ofsaid lock means-from said stop-meansandreverse rotation. of said a 2.
